在制作数据可视化大屏时，尤其是在触摸屏演示时，需要开发和设计对应的数据大屏引导页。基于常见场景，单独开发数据大屏引导页。

前端可自行配置大屏引导页背景图、标题信息；
前端可自行引导菜单（根据大屏的特殊要求，案例菜单最多6个，最少1个）；
基于php原生代码开发，未使用任何模版引擎；
适合于菜鸟入门使用；

在这里插入图片描述

1.引入外部js库

项目使用到layui.js的图标和弹窗功能，因此作为常备js库引入页面；其他都外部文件为项目自定义文件。

 <script type="text/javascript" src="js/jquery.min.js"></script>
    <script type="text/javascript" src="js/functions.js"></script>
    <!--layui封装库-->
    <script src="js/layui/layui.js" charset="utf-8"></script>
    <link rel="stylesheet" href="js/layui/css/layui.css">
    <!--核心样式表-->
    <link rel="stylesheet" href="css/common.css">

2.HTML排版

为实现大屏背景的自行配置，body的背景css直接写在了页面中，通过style="background: #0a0d26 url('./images/mainbg1.jpg')进行代码的切换。

<body style="background: #0a0d26 url('./images/mainbg1.jpg') no-repeat top center; ">
<div class="panel">
    <div class="title">
        <p>科为数据可视化服务中心</p>
        <p>Kewei Data Visualization Service Center</p>
    </div>
    <div class="guid_menu">
                                <a href="https://www.baidu.com/"><div class="subMenu sub_bg1">
                <p><i class="layui-icon layui-icon-website"></i></p>
                <p>数据中心</p>
                <p>Kewei Service</p>
            </div></a>
                                <a href="https://www.baidu.com/"><div class="subMenu sub_bg2">
                <p><i class="layui-icon layui-icon-upload-drag"></i></p>
                <p>用户中心</p>
                <p>Kewei Service</p>
            </div></a>
                                <a href="https://www.baidu.com/"><div class="subMenu sub_bg3">
                <p><i class="layui-icon layui-icon-user"></i></p>
                <p>后台管理</p>
                <p>Kewei Service</p>
            </div></a>
                                <a href="https://www.baidu.com/"><div class="subMenu sub_bg4">
                <p><i class="layui-icon layui-icon-set"></i></p>
                <p>服务支持</p>
                <p>Kewei Service</p>
            </div></a>
                                <a href="https://www.baidu.com/"><div class="subMenu sub_bg5">
                <p><i class="layui-icon layui-icon-app"></i></p>
                <p>产品概况</p>
                <p>Kewei Service</p>
            </div></a>
                                <a href="https://www.baidu.com/"><div class="subMenu sub_bg6">
                <p><i class="layui-icon layui-icon-tabs"></i></p>
                <p>城市管理</p>
                <p>Kewei Service</p>
            </div></a>
            </div>
</div>

3.项目配置文件

项目配置文件位置:conf/config.php。初始代码如下，可以通过表单进行全局更新。

<?php return [
    'sys_title' => '数据可视化服务中心',
    'sys_title_en' => 'Data Visualization Service Center',
    'sys_bg_img' => './images/mainbg3.jpg',
    'links' => [
        ['title' => '数据中心', 'links' => 'http://www.baidu.com/'],
        ['title' => '用户中心', 'links' => 'http://www.baidu.com/'],
        ['title' => '后台管理', 'links' => 'http://www.baidu.com/'],
        ['title' => '服务支持', 'links' => 'http://www.baidu.com/'],
        ['title' => '产品概况', 'links' => 'http://www.baidu.com/'],
        ['title' => '智慧城市', 'links' => 'http://www.baidu.com/']
    ]
];

4.菜单图标自动匹配

通过循环配置文件conf/config.php中’links’数据，来判断不同菜单的坐标显示方式。

function getIcon($num)
{
    switch ($num) {
        case 1:
            echo 'layui-icon-website';
            break;
        case 2:
            echo 'layui-icon-upload-drag';
            break;
        case 3:
            echo 'layui-icon-user';
            break;
        case 4:
            echo 'layui-icon-set';
            break;
        case 5:
            echo 'layui-icon-app';
            break;
        case 6:
            echo 'layui-icon-tabs';
            break;
        default:
            echo 'layui-icon-website';
    }
}

5.php与html混排

示例代码为生产环境下，php和 html共同作用展示项目内容。

<body style="background: #0a0d26 url('<?php echo $DATA['sys_bg_img'] ?>') no-repeat top center; ">
<div class="panel">
    <div class="title">
        <p><?php echo $DATA['sys_title'] ?></p>
        <p><?php echo $DATA['sys_title_en'] ?></p>
    </div>
    <div class="guid_menu">
        <?php for ($i = 0; $i < count($DATA['links']); $i++) { ?>
            <?php if ($DATA['links'][$i]['title'] !="" && $DATA['links'][$i]['links'] !="") {?>
            <a href="<?php echo $DATA['links'][$i]['links'] ?>"><div class="subMenu sub_bg<?php echo ($i + 1) ?>">
                <p><i class="layui-icon <?php getIcon(($i + 1)) ?>"></i></p>
                <p><?php echo $DATA['links'][$i]['title'] ?></p>
                <p>Kewei Service</p>
            </div></a>
        <?php }} ?>
    </div>
    <div class="copyright"><p><span onclick="getZoomUrl('导航链接', 'links.php', '', '', '')"><i class="layui-icon layui-icon-component"></i> </span>  备案号：<a href="https://beian.miit.gov.cn/" target="_blank">粤ICP备2022021238号-2</a> </p></div>
</div>

6.CSS样式表

主要是导航菜单的CSS

/*导航菜单*/
.guid_menu {
    text-align: center;
    margin: 5% 0 10% 0;
    width: 100%;
}

.subMenu {
    display: inline-block;
    color: #fff;
    text-align: center;
    padding: 2%;
    margin: 0 1%;
    border-radius: 5%;
}

.sub_bg1 {
    background-image: linear-gradient(-120deg, #c8d138, #51933b);
}

.sub_bg2 {
    background-image: linear-gradient(-120deg, #31c9a3, #107392);
}

.sub_bg3 {
    background-image: linear-gradient(-120deg, #4ccaf3, #326eea);
}

.sub_bg4 {
    background-image: linear-gradient(-120deg, #4a8fea, #1749bc);
}

.sub_bg5 {
    background-image: linear-gradient(-120deg, #5451e8, #611eb9);
}

.sub_bg6 {
    background-image: linear-gradient(-120deg, #bb3a8c, #ba6e3d);
}

.subMenu:hover {
    background: #cc0058;
    cursor: pointer;
}

.subMenu > p {
    margin: 8px 0;
    font-family: "宋体";
}

.subMenu > p:first-child > i {
    font-size: 26px;
}

.subMenu > p:nth-child(2) {
    font-size: 18px;
    font-weight: bold;
}

.subMenu > p:nth-child(3) {
    font-size: 10px;
    color: rgba(255, 255, 255, 0.5);
    font-family: "Arial";
}

7.添加/编辑信息

在这里插入图片描述

<div class="layui-fluid" style="margin-top: 20px;">
    <form class="layui-form layui-form-pane" lay-filter="component-form-group">
        <div class="layui-card">
            <div class="layui-card-header" style="font-weight: bold;text-align: center;">导航链接配置</div>
            <div class="layui-card-body" style="padding: 15px;">
                <div class="layui-form-item">
                    <label class="layui-form-label">系统标题<span class="x-red">*</span></label>

            </div>
        </div>
    </form>

8.生成配置文件

$act = $_GET['act'];
if ($act == "annual") {
    $sys_title = $_POST['sys_title'];
    $sys_title_en = $_POST['sys_title_en'];
    $sys_bg_img = $_POST['sys_bg_img'];
    $title1 = $_POST['title1'];
    $links1 = $_POST['links1'];
    $title2 = $_POST['title2'];
    $links2 = $_POST['links2'];
    $title3 = $_POST['title3'];
    $links3 = $_POST['links3'];
    $title4 = $_POST['title4'];
    $links4 = $_POST['links4'];
    $title5 = $_POST['title5'];
    $links5 = $_POST['links5'];
    $title6 = $_POST['title6'];
    $links6 = $_POST['links6'];

    //生成数据分表的配置文件config.sys.php
    $config_table = "<?php return [
    'sys_title' => '" . $sys_title . "',
    'sys_title_en' => '" . $sys_title_en . "',
    'sys_bg_img' => '" . $sys_bg_img . "',
    'links' => [
        ['title' => '" . $title1 . "','links' =>'" . $links1 . "'],
        ['title' => '" . $title2 . "','links' =>'" . $links2 . "'],
        ['title' => '" . $title3 . "','links' =>'" . $links3 . "'],
        ['title' => '" . $title4 . "','links' =>'" . $links4 . "'],
        ['title' => '" . $title5 . "','links' =>'" . $links5 . "'],
        ['title' => '" . $title6 . "','links' =>'" . $links6 . "']
        ]
    ];";

    //对应文件夹具备权限;
    @file_put_contents('conf/config.php', $config_table);

    $res['code'] = 1;
    $res['msg'] = "配置成功";
    die(json_encode($res));
